Technical specifications

This table gives a clear breakdown of the main technical specs so you can compare with your current battery or with product listings.

How to interpret these specs

You’ll note the distinction between nominal and marketed voltages; the battery is a 51.2V pack commonly sold as a 48V replacement. The 100Ah rating gives you over 5 kWh usable if you use most of the capacity; with LiFePO4 you can often use a larger percentage of the pack than with lead-acid. The BMS ratings and continuous current are key for high-draw devices like motors.

Performance and capacity in real use

You want to know how it performs when powering your cart, boat motor, or off-grid system. Real-world performance depends on discharge rates, ambient temperature, and how you charge and maintain the battery.

• Range and runtime: With 5.12 kWh nominal capacity, your runtime depends on motor draw. For a golf cart drawing 1–2 kW continuous, you should expect multiple hours of use compared to lead-acid where usable capacity is often much lower.
• Power delivery: The 200A continuous rating lets you run high-draw applications like heavy loads, steep terrain, or trolling motors with fewer voltage sag issues.
• Efficiency: LiFePO4 chemistry offers higher round-trip efficiency than lead-acid, so you’ll get more usable energy per charge cycle.

What you’ll notice day-to-day

You’ll probably notice more consistent voltage under load, faster acceleration on a cart, and less range reduction over time. Because the battery holds voltage better than lead-acid, accessories and electronics will run more reliably at lower states of charge.

Built-in 200A BMS — what it does for you

The integrated Battery Management System is one of the most important features you’ll use every day. It keeps the pack safe and helps prolong cell life.

• Protection functions: The BMS guards against overcharge, over-discharge, over-current, and short circuits so you don’t need to worry about immediate catastrophic failures.
• Thermal cutoffs: Charging will stop above 50°C (122°F) to prevent thermal stress, and the low-temp cutoff prevents charging below freezing to protect cell health.
• Current handling: With a 200A limit, the battery can support substantial continuous loads and manage short-term peaks.

Why the BMS matters to you

If you’re switching from unprotected lead-acid, you’ll appreciate the peace of mind. The BMS reduces the chance of damage from wiring faults or misuse and helps the cells age more gracefully so you get closer to the advertised 5,000+ cycle life.

Durability and lifespan

You’ll want a battery that lasts, especially given the higher upfront cost of LiFePO4 compared to lead-acid.

• Cycle life: Rated at 5,000–15,000 cycles depending on depth of discharge, you’ll see a long lifespan if you use moderate depth-of-discharge and proper charging practices.
• IP65 protection: The casing protects against dust and sprays of water, making it suitable for outdoor and marine environments.
• Expected service life: If you cycle the battery daily at moderate depths, you can expect many years of useful life—often over 10 years under normal conditions.

Managing expectations

Performance varies based on how hard you use the battery. If you frequently push depth-of-discharge to 100% or operate in extreme temperatures, the life will skew to the lower end. If you keep discharge shallow, maintain stable temperatures, and use an appropriate charger, you’ll approach the upper bound.

Temperature and environmental behavior

Temperature affects charging, discharging, and longevity, and this battery includes several protections for extreme conditions.

• Cold conditions: The battery includes a low-temp cut-off to prevent charging below roughly 0°C±4°C (32°F±7.2°F) because charging at low temperatures can damage cells.
• Heat protection: Charging is inhibited above 50°C (122°F) to prevent thermal damage, and the BMS monitors for over-temperature events.
• Operating range: Discharging is allowed at lower temperatures down to around -20°C±4°C (-4°F±7.2°F), though performance (capacity and power) will decline in the cold.

Practical advice for extreme climates

If you store or use batteries in freezing conditions, warm them before charging. If you operate in hot climates, provide shade or ventilation to help keep the battery under the high-temp cutoff threshold during charging.

Weight, size, and installation

If your cart is heavy with lead-acid, swapping to LiFePO4 is a game-changer. You’ll notice reduced weight and simplified installation.

• Weight savings: The pack weighs about one-quarter of a comparable lead-acid battery bank, and that commonly saves 200 lbs or more for a golf cart setup.
• Fitment: The size is designed to be compatible with many carts (Club Car, EZGO, ICON, Yamaha), but you’ll want to verify dimensions for your battery box.
• Installation: Wiring is typically straightforward with fewer individual battery blocks to connect, but correct polarity and secure connections are critical.

Installation tips you’ll want to follow

Always disconnect the old batteries fully, inspect and clean terminals, and use cables rated for the current you plan to draw. Consider a professional install if you’re not comfortable with battery wiring and electrical systems.

Bluetooth connectivity and monitoring

You’ll get convenience from the integrated Bluetooth feature that lets you monitor battery status from a phone.

• Real-time monitoring: See state of charge, voltage, current, and sometimes cell-level info depending on the app.
• Smart checks: You can confirm charging state and discharge behavior without direct meter probes.
• Remote troubleshooting: If something goes wrong, the Bluetooth readouts help you or a technician diagnose BMS trips or abnormal behavior.

How to use Bluetooth effectively

Install the manufacturer’s app, pair it with the battery, and check periodically. The data will help you optimize charging schedules, confirm health, and avoid surprises during outings.
